An applicant or applicant’s consultant shall first submit a Transportation Impact Analysis (TIA) Determination Worksheet to the Transportation Development Services (TDS) Division’s TIA Determination Portal for review. The worksheet contains trip generation information and details of the proposed development including, but not limited to, project location, land use, access points, density, phases of site construction, and timeline for occupancy.

TDS will perform the determination and sign the worksheet. If applicable, TDS will direct the applicant to submit a TIA Scope to the TDS Division’s TIA Portal for review.

An applicant submitting a site plan, zoning, or rezoning application must submit a TIA if the expected number of vehicular trips generated by a project exceeds 2,000 vehicle trips per day. The type of TIA required will depend on the application being submitted and the net new daily trips generated; more information on the types of TIAs available can be found in Section 10 of the Transportation Criteria Manual.

For a project or development for which a TIA is not required, a mitigation assessment shall be performed to identify transportation needs in the area that the applicant may choose to construct. These improvements may be credited as offsets to a development’s Street Impact Fee requirement if they are determined to be eligible. Please refer to the Street Impact Fee website for additional information. The respective TDS project manager or lead development review engineer will coordinate with the applicant regarding possible mitigation options.
